nears s'r vres PTENT REFRIGERATOR DISPLAY CASE.

Application filed July 9,

This invention relates to refrigerator display cases and has for itsobject the provision of a display case of this character which is ofsuch interior construction as to enable the proper temperature to bemaintained within the case by periodical circulation of a refrigeratingmedium through a cooling coil located in the central portion of thecase.

A further purpose of the invention is to provide a display case of thecharacter stated in which the article supporting shelves are of thelattice type and arranged to extend from opposite sides of the coolingcoil to the ends of the case.

Other purposes and advantages of the invention as well as the details ofconstruction and combination of parts characterizing the embodimentherein disclosed will be more readily understood from the followingdescription taken in connection with the accompanying drawings in which-Figure 1 is a front elevational view of the refrigerator display case.

Figure 2 is a rear elevational view of the refrigerator display case.

Figure 3 is a sectional view taken along the line 3-3 of Figure 1.

Figure 4 is a sectional View taken along the line lf of Figure 1, and

Figure 5 is a sectional view taken along the line 55 of Figure 4.

Proceeding now to a more detailed discussion of the drawings, 5designates a rectangular floor engaging frame upon which the-case, desinated as a whole by reference character 6, is adapted to be supported.One sid of the frame 5 is hinged, as 7, to the case 6 to permit accessto a drip pipe 8 carried by a metal pan 9 constituting the bottom of thecase. This pan 9 is secured to and closes the center of a substantiallyrectangular base frame 10 upon which are supported the side and endwalls of the case as hereina ter described.

The front wall of the case is formed, in the present instance, by twoglas panels 11 and 12, made of any dc 'red thi joined at their innervertical edges to an intervening wooden panel provided at the inner sidewith coil; or other suitable heat insulating lining 1. L Tic outervertical edges of the panels 11 and 12 are joined to the front cornerposts 15 and 16. The ends of the case are formed by the glass panels 17and 18 having their front vertical edges s clrness and 1926. Serial No.121,449.

secured to the aforesaid front corner posts 15 and 16 and their rearvertical edges secured to the rear corner posts 19 and 20.

The rear wall of the case is formed by a plurality of verticallyextending members 21 and horizontally ext-ending members 22 arranged todefine a plurality of door openings closed by suitable doors 23, certainof said doors being hingedas at 24 to the front corner posts of the caseand the remaining doors being hinged as at 25 to an insulated woodenpanel 26 forming the central, part of the rear wall and correspondinginstructure to the opposing panel 13.

The side and end walls of the case, hereinbefore described, serve tosupport thereon a rectangular top frame 27 carrying a metal glassholding frame 28 in which is secured the glass cover panel 29.

At each side of the panels 13 and 26 the front and rear walls of thecase are connected by vertically spaced shelf supports 30 aligned withcomplementary supports 31 extending across the end portions of the case.Carried by these supports are a plurality of shelves 32 of open work orlattice type which serve to divide the interior of the case at each sideof said panels into a. plurality of superimposed compartments. The spacebounded by the panels 13 and 26 and the shelf supports 30 constitutes acoil receiving chamber in which is arranged a vertically extendingcooling coil 33 made substantially oval in shape and preferablysupported in upright position by the said shelf supports 30. The coil ismade oval shaped so as to extend substantially the full width of thecase between panels 13 and 26 with the flattened portions of the coilspaced apart to take up the full width of the cooling chamber r servedbetween the opposing shelf supports 30.

The terminal portions 84 and 35 of the coil 33 may be carried outwardlythrough the case as shown in Figure 5 or in any other desired manner forconnection to a suitable type of refrigerant circulating apparatus.

In the use of the refrigerator display case described in the foregoingit has been found that a periodical circulation of a refrigerating agentthrough the coil 33 is sufficient to maintain the air in the case at avery low temperature. This naturally results in a considerable savingwith respect to the operating cost of the refrigerant circulatingapparatus as compared with the known prior types of refrigerating casesrequiring contin uous circulation of the cooling agent there-- throughin order to maintain the desired temperature. This advantage of thepresent invention is attributed to the interior construction of the caseincluding the specific arrangement of the lattice Work shelves and thespecific location and shape of the cooling coil 33.

Having described in the foregoing my present conception of the preferredembodiment of the invention it Will he understood that various changesin construction and assembly of parts may he resorted to Within thescope and spirit of the invention as de fined by the appended claims.

What I claim is:

1. A refrigerator display case, a vertically extending cooling coilarranged therein, a plurality of shelves extending from opposite wallsof the case to opposite sides of the coil, and a plurality of shelfsupports carrying said shelves and extending transversely across thecase, the supports at the inner ends of the shelves engaging the sidesof the coil to maintain the latter in upright position.

2. A refrigerator display case including front and rear insulated panelsforming the central portions of the front and rear Walls of the case, avertically extending cooling coil arranged in the case between saidpanels, shelves extending from each end of the case to the adjacent sideof the coil and a plurality of shelf supports extending across the caseimmediately adjacent each side of said panels and serving to support theinner ends of said shelves and to engage the sides of the coil tomaintain the latter in upright position Within the space bounded by saidpanels and shelf supports.

In testimony whereof I hereunto my signature.
